Abstract

According to embodiments, a base station includes a radio communication unit configured to establish communication with a mobile communication terminal using a plurality of component carriers. The base station further includes a control unit configured to transmit a command to the mobile communication terminal to reduce 10 the plurality of component carriers to one prior to handover of communication between the mobile communication terminal and the base station to another base station.
